86_FS10.pm is for reading ELV (www.elv.de) weather Sensors, using a Hardware
(Part No. 68-390-61) and communicates with pcwsd from Sven Geggus.

Currently temperature, windspeed, rain and brightness sensors are supported.

For use with FHEM you have to compile pcwsd like usual, it can be found here
  http://geggus.net/sven/pcwsd/

Start pcwsd deamon with
  pcwsd -d /dev/ttyUSB4 -ld /var/log/fs10- -tlf %Y-%m-%d_%T

A few minutes later you should see files with temperature values.

For use with FHEM define

define fs10 FS10 127.0.0.1 4711 which means pcwsd run on localhost, port 4711 

If you only interested in viewing temperature values with a FHEM frontend like
pgm3, 86_FS10.pm can be ommited.

To display a user defined FS10 temperature graphic in pgm3 define
